THEODORE R. TIMBY, OF NYACK, NEW YORK.

ORE-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 225,665, dated March 16, 1880.

Application filed August l, 1879.

To all whom it may concern:

Be it known that I, THEoDoRE R. TIMBY, of Nyack, Rockland county, New York, have invented certain new and useful Improvements in Apparatus for Crushing Orcs, Quartz, Feldspar, and other Rocks, of which the following is a specification.

My present invention embodies that form of ore or rock crushing apparatus patented to me July 22, 1879 in which the material is crushed by steady compression in layers between a series of disks within an inclosingcylinder; 'and the main feature of my present invention lies in a grouped arrangement of these cylinders about a revolving axis mounted in a rigid frame, whereby one cylinder may be filled, the contents of another crushed, and the contents of a third removed after crushing without loss of time or mutual interference.

The present invention also consists in the special construction of the interior of the cylinder and of its disks, by which the material may be crushed without danger of contact or admixture with objectionable metallic matter, as hereinafter fully set forth.

Figure l of the annexed drawings presents a front elevation of my improved apparatus Fig. 2, a plan view thereof; Fig. 3, a vertical section on m, viewed in direction of the arrow, and Fig. 4 an inverted plan.

As illustrated, a a indicate a strong upright frame-work, in which a series or group of cylinders, b c d, are mounted. The cylinders are preferably three in number, as shown, and are preferably arranged vertical, and are mounted between the strong fixed heads e e of the frame a, the cylinders being arranged radially around a central axis or shaft, f, which is ixed at each end to strong rotating heads g g', in which the ends of the cylinder are secured, while the opposite ends of the shaft are journaled in the fixed heads e e of the stationary frame, as illustrated, thus rendering the group of tubes rotatable between the fixed heads e e within the stationary frame a.

The upper head, e, of the frame has a series of three circular openings, 1 2 3, as shown best in Fig. 2, corresponding to the bores of the group of cylinders b c d, while the lower head, c', has but one opening, corresponding to one of the cylinders, as illustrated in Figs. 3 and l, so that hence the bottom openings of two of the tubes are always closed by the lower head, e.

In operating the apparatus the material to be crushed is charged through the opening l into the cylinder in position beneath it; after which the group of cylinders is shifted around one space, thus bringing the filled cylinder beneath the opening 2, over which the plunger l of a hydraulic or other suitable press is located, and which is arranged to enter the cylinder at this position and crush its charge. After this crushing action the plunger retires from the cylinder, and the group is again shifted another space, bringing the cylinder, with the crushed charge, over the opening in the bottom head, e', through which the material is discharged into the space below the head, as shown in Figs. l and 3, from which it is removed as required.

It will hence be seen that by this arrangement one cylinder of the group may be filled, the contents of the other crushed, and the contents of the third discharged simultaneously, without the several actions interfering with each other, thus enabling the work to be performed with convenience and rapidity.

It will be readily understood that the group of tubes may be shifted or revolved, and held in the desired position by any suitable mechanical device, such as a worm and wormwheel.

It will be also understood that in charging the cylinders with the quartz or other material, it is arranged in layers between disks h h, as shown in Fig. 3, according to the inode described in my former patent, above cited.

The cylinders or tubes b c d are preferably formed of wrought or cast iron, and of suitable thickness to obtain the necessary strength, and one feature of my present invention consists in lining their interior with a layer of wood, as indicated at 7s k, or other non-metallic fibrous material cemented to the bore of the tube or attached in other suitable manner.

Another feature of my invention consists in forming the disks h h of a similar non-metallic IOO brous material, preferably of layers of paper cemented together and compressed to great hardness, as indicated in lFig. 3.

This construction of the interiorof the cylinders and of the disks thus obviates the contact or fainting of the charge with metallic matter, which, in the case of feldspar and quartz for the manufacture of porcelain, would be almost a fatal objection, as when the latter is admiXed or tainted with particles of iron it becomes unfit for its purpose; but by means of my improvement it maywthus be crushed and discharged in a pure condition.

In some cases the disks h h may be formed with a metallic core, with a complete outer envelope or covering of compressed paper or other equivalent non-metallic material; but I prefer to form the disk Wholly of non-metallic material.

What I claim as my invention is l. An ore-crushing apparatus formed With a series of tubes or cylinders grouped about a rotatable axis mounted in a rigid frame, whereby one tube may be charged and the contents of the others respectively crushed and removed simultaneously, substantially as herein shown and described.

2. The combination of the rigid frame a, perforated fixed heads c e', and rotatable group of tubes b c d, mounted between said heads, substantially as shown and described.

3. In a quartz or rock crushing apparatus, substantially such as described, a metallic cylinder for inclosing the rock While being crushed, and having a non-metallic fibrous lining, substantially as and for the purpose herein set forth.

4. In a rock or quartz crushing apparatus, the non-metallic brous disks interposed between the plunger and the bottom of the cylinder, substantially as and for the purpose specified.
